TI 83 Plus “Ram Cleared” Error Fix

My old TI 83 Plus calculator recently started showing the “Ram Cleared” error and then restarting when using it, which was quite annoying.

I replaced the backup button battery, which is located in the center of the back, but it did not work. Then finally I opened the whole back cover and noticed the green corrosion at the two battery contact points on the circuit board.

I cleaned the corrosion using rubbing alcohol and bent the spring ends so that the contacts are solid. (I also soldered it a little to smooth the dents, which is not necessary. )

After putting everything back, the calculator is normal again.

Here are what you need:

  1. A T6 torx screwdriver to remove the four corner screws. The bottom two are pretty deep.
  2. A Phillips screwdriver to remove the center screw.
  3. Rubbing alcohol & a cotton ball or wipe to clean.

Good luck.

Dexas MudBuster Portable Dog Paw Washer/ Paw Cleaner

Dog paws tend to attract lots of dirt or mud after the outdoor walking especially after rain or snow. Wipes help, but it may take quite a few pieces for cleaning up.

Dexas MudBuster Portable Dog Paw Washer has soft silicon bristles inside the cup. Using just water, it cleans paws much better than my bare hand cleaning. I then use a bath towel to dry the paws up after washing.

Zesty Paws Allergy Immune Supplement for Dogs

My dog developed skin allergy in last spring, and and she kept licking her belly and had severe hair loss there. We tried quite a few shampoos, body washes, and the Vet recommended Benadryl. None of them really helped. We kept trying until one day we found Zesty Paws Allergy Immune Supplement for Dogs.

It is a grain free chew and contains LOTS of ingredients including colostrum (pre milk), vitamins, antioxidants, prebiotics and probiotics…. I fed my medium sized dog two chews a day, and surprisingly, she stopped licking and the losing hair grew back after a few weeks.

I am not sure which ingredient worked, or if it will work for other type of allergies. Amazon has more than 15,000 reviews on this product with a average rating 4.3 out of 5 as of today.

SportDOG Brand 425X Remote Trainers

SportDOG FieldTrainer 425X is a highly rated E-collar system for dog training or hunting. The E-collar fits dogs 8 pounds and up, and it is also claimed to be waterproof for and submersible to 25 feet.

I have an older version SD 425 for a few years and it is quite reliable. It has seven static stimulation levels, plus a vibration and a beep function. It is claimed to have 500 yards of range, but I never tested that far. I use it mostly for my dog wandering in my yard as a moving invisible fence, and when she is too close to the boundary, I just press one button on the transmitter and the E-collar will send a beep sound, and she will stop and turn back. When just started the training. If the dog keeps going forward, a mild shock may be sent from another button.

For the stimulation I use levels 2 and 3 the most often. When the dog hair is long or the battery level is low, I have to either use a tighter fit for the collar or increase the shock level. I often try on my fingers before put it on my dog. Level 4 is really uncomfortable. The shock will make the finger muscles shrink, and feel sour and numb. I rarely go above level 4.

Both the transmitter and E-collar are rechargeable and they can be charged at the same time. It is claimed to last 50 to 70 hours for a two-hour charge. As I only use for a short time each day, it may last for about two months after a full charge. When the battery is low, the yellow-green indicator light on the E-collar will turn red.

Pet Stain and Odor Eliminator

Stains and odor are often headaches to many families with pets (such as cats or dogs). Especially during potty training or when pets are sick and throw up on your carpet. All you wish was to have something at hand to clean up the mess immediately.

Rocco & Roxie Professional Strength Stain and Odor Eliminator worked best for us. We usually spray this on the carpet stains and wipe thoroughly with paper tower. We also apply Lysol disinfection spray at the end for the peace of mind.
